VALVE.

SPECIFICATION forming part of Letters Patent No. 740,807, dated October6, 1903. Application filed deptemher 23, 1901. Serial No. 76,21. (Nomodel.)

. To ctZ-Z whom it may concern:

. same on line 2 2, Fig. 1.

Be it known that I, JOHN H. CLUNE, a citizen of the United States ofAmerica, residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements in Valves, ofwhich the following is a specification.

This invention relates to valve construction, and especially toself-closing basin-cocks, the object of the invention being to provide acock of this type which shall close by the action of the water behind itand which shall be of simple construction and provided with a valve-seatlocated in or near the end of the nozzle of the cock and removabletherefrom from the outside, all as fully set forth and claimed in thefollowing specification.

In the drawings forming part of this specification, Figure 1 is alongitudinal sectional view of a cock constructed according to myinvention. Fig. 2 is a cross-section of the Fig. 8 is a section on line3 3, Fig. 1, showing the valve partly broken away. Fig. 4 is a view ofthe valveseatin plan and vertical section and slightly modified inconstruction.

Referring to the drawings, the body of the cock is indicated by 2 and isof the usual form and is provided with the down-hanging nozzle 3. Thisbody is preferably divided, as

at 4, and the two parts screwed together, to the end that after it hasbeen applied to a service-pipe, as it frequently is by being wiped on,the body may be unscrewed. for the purpose of removing the valve shouldoccasion arise. If the body he made to screw onto a service-pipe or besecured thereto by a union, the division of the body at t would besuperfluous.

Transversely of the horizontal axis of the body and at a suitabledistance from the nozzle end there is located the stem 5, on which thereis non-rotatably secured the arm 6, carrying at its outer freeend thevalve 7, preferably cast integrally with said arm.

To supportthestem 5, I prefer to casttwo bosses 8 and 9 on the interiorsurface of the body 2, one of which, 8, is provided with a socket toreceive the inner end of said stem,

which is inserted through a hole made through the other boss, 9, fromthe outside of said body.

Preferably the stem is squared where it receives the arm 6. That part ofthe stem which projects through the body of the cock to receive ahand-wheel 10 or other handle is provided with a packing-gland 11, madein the usual manner, the nut of which screws into a boss formed on thebody and compresses the packing=ring 12 around the stem. That portion ofthe latter which passes through the gland 11 is turned down to a smallerdiameter than that part located in the boss 9, whereby a shoulder 13 isformed thereon, and before the packing is put in place a metal washer 14is slipped onto the stem to bear against said shoulder, being heldthereagainst by the nut of said gland to prevent endwise movement of thestem in one direction.

The seat for the valve is indicated by 15 and preferably is madecone-shaped,as shown, and is screwed or otherwise removablysecured in ornear the end of the nozzle of the cook. The valve 7 is turned out (11its under side to conform to the taper of the seat 15, and thetransverse diameter of the valve is such as to leave only acomparatively narrow waterpassage around said valve. Furthermore, thearm, 6 is so proportioned that when it is manipulated to raise the valvefrom its seat the former cannot be raised far enough to take it out ofthe current of water flowing through the nozzle, to the end that whenthe arm is released the water-pressure on the up- .per side thereof willalwayscause the valve to close.

Instead of making a tapered fit betweenthe seat and the valve the seatmay be fitted with a ring-seat 16, as shown in Fig. i, which may be madeof softer material than said tapered seat, or, if desired, the seat maybe horizontal, as in the'ordinary globe-valve.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

v 1. In a basin-cock having the usual downhanging nozzle, a valvemovable vertically in the latter, a valve-seat secured to or near theend of the. nozzle below the valve, a curved arm on which the valve issupported extending back into the body of the cook, a valvestemextending through the side of the cock at right angles to said arm, thelatter and said stem being secured together to move as one piece.

[0 ported in said cock, a valve thereon depending from the end of saidarm into the nozzle and vertically movable only within the limits of thelatter, and a seat in said nozzle for said valve, said seat beingremovable through said nozzle from outside the cock, substantially as I5described.
